Now if your drive is working go and copy quick all the data you can and if not throw it out tho the garbage or send it to the manufacturer.
Shorting read channels:short the pins shown here

this is the component side, it goes through the pcb to the other side, I think here

Thanks everyone. I fixed my ST31000528AS 1TB Barracuda 7200.12 Firmware:
CC49 model hdd with help of that and with another command.
At first I have to say my aim for fixing it was to USE it. Not for data recovery but it was surprising when I saw 2. and 3. partitions (with files in them) on my hdd were't deleted after my fix.
I used soldering,may be you don't have to but if you will then it is your own risk.My mobo couldn't see hdd in bios or hot swap. It was after a low voltage and psu failure.
I tried a lot of things but always got an error

Then I looked at connections on the PCB and measered the diots with a cheap and simple multimeter and found these diodes on SATA DATA connection are not working. I soldered them to disable / by-pass them. After soldering; data flows from SATA port to PCB like there is no diode. Don't solder any diode with another one.

You can see 3 other diodes next to the ones that I marked. They were running OK in my hdd but if not in yours, you can solder them.
Then I tried the commands with the help of a DKU-5 cable. But I got "Inıt SMART fail" errors and I did like that:

After that I removed DKU-5 cable connections and atteched hdd to computer and restart. It was visible on BIOS and windows saw hdd with all partitions. I tried seagate tools -both windows and dos but couldn't full erase disk to fix bad sectors. I am running hdtune and erasing it, if that won't work, I will learn where bad sectors are with its Error Scan and setup a couple of partitions to use hdd.
good luck.
